No, the heart muscles do not have the same structure as the armmuscles.
The specialized muscle tissues which form the heart are called the cardiacmuscles. The cardiac muscle tissues are unique in the sense that they are only present in the heart and nowhere else in the body.
The specialized cells that form the cardiac muscle tissues are called cardiomyocytes.
Cardiomyocytes are also muscle cells and thus like other muscle cells, they rely on actin and myosin for their contractions. The cardiomyocytes have a high number of mitochondria as the heart muscles need a high amount of energy for their functioning.
The cardiac muscle fibers are thick and branched structures, specialized in contracting and pumping the blood.
Purkinjefibers are a kind of specialized cells present along with the cardiac muscles that help in the transmission of electric impulses to the heart and from the heart.
Therefore, the heartmuscles do not have the same structure as the arm muscles.

The fluctuations in abiotic cycles can influence the population in many ways. The population of a particular area depends on the various abiotic cycles such as nitrogen cycle, carbon cycle, phosphorous cycle. The changes in these cycles affects the life of population. Fluctuation results in hibernation of species. Some of the organisms migrate to another place in search of normal environment. The early breeding results in creating problems. It disturbs the ecological balance by using the limited supply of resources. The fluctuation in phosphorous cycle can affect the aquatic population. As the dependency of population on abiotic cycles is as important as the biotic factors the fluctuations can cause many problem.

A codon is made up of three nitrogen bases in an RNA molecule, each coding for a specific amino acid. It is an essential concept in understanding the production of proteins.
A codon in the biological context consists of three nitrogen bases. These nitrogenous bases are part of an RNA molecule. The bases can be adenine (A), guanine (G), cytosine (C), or uracil (U). Each codon represents and codes for a specific type of amino acid. As a result, a sequence of codons provides instructions for the construction of a protein. This is vital to understanding the central dogma of molecular biology—DNA makes RNA and RNA makes protein.
